I want to complete the credits. From the game manuals or the staff rolls, below are apparently listed;
KF: Koji Endo, Kaoru Kono
KFII:
SOUND KID'S Corp.
KFIII:
SOUND KID'S Corp.
KFIV: Tsukasa Saitoh, Yuji Kanda, Yuki Ichiki
I never listened to
KING'S FIELD original besttrack, but does it complete the in-game music of KFI? (KFI has never been released outside of Japan, but I hope somebody can answer this), if so, I think it's safe to go with "Koji Endo, Kaoru Kono, SOUND KID'S Corp." for the said album.
This album, on the other hand, is likely to be incomplete, and we don't know who scored Additional I&II...
